Die Erfindung bezieht sich auf eine Vorrichtung zum Behandeln von Folienbahnen aus thermoplastischem Kunststoff mittels Koronaentladungen mit einer an einen Hochspannungsgenerator angeschlossenen Walzenelektrode und einer im Abstand von der über die Walzenelektrode führbaren Foiienbahn angeordneten Gegenelektrode.The invention relates to a device for treating thermoplastic film webs Plastic by means of corona discharges with a connected to a high voltage generator Roller electrode and a film web that can be guided over the roller electrode at a distance arranged counter electrode.

Bei den bekannten Vorrichtungen dieser Art bilden der Hochspannungsgenerator und die eigentliche Behandlungsvorrichtung getrennte Baueinheiten.In the known devices of this type, the high-voltage generator and the actual Treatment device separate units.

Der Erfindung liegt die Aufgabe zugrunde, eine raumsparende Konstruktion zu schaffen.The invention is based on the object of creating a space-saving construction.

Diese Aufgabe wird erfindungsgemäß dadurch gclöst, daü der Hochspannungsgenerator innerhalb der Walzenelektrode angeordnet ist.According to the invention, this object is achieved by that the high-voltage generator is arranged within the roller electrode.

Bei einer vorteilhaften Ausführungsform der Vorrichtung gernäß der Erfindung weist die Walzenelektrode zur Aufnahme des Hochspannungsgenerators höherer FrequenzIn an advantageous embodiment of the device according to the invention, the roller electrode to accommodate the high-voltage generator of higher frequency

Da die Hochspannung an dem völlig gekapselten Isolierstoffrohr 3 anliegt und die Gegenelektrode 5 auf Masse geschaltet ist, können in erhöhtem Maße die Bcdicnungssehutzvorschiiften eingehalten werden. Since the high voltage is applied to the completely encapsulated insulating tube 3 and the counter electrode 5 is connected to ground, the safety regulations can be complied with to a greater extent.
